更換Windows Mobile 6.5 標題列和功能表列背景

更換Windows Mobile 6.5 標題列和功能表列背景

     在Windows Moible 6.5上添加了新特性。下面是微軟定義的關於設定Task bar和softkey bar的訊息定義，訊息定義的很清楚。

 

// Retrieve the alpha value for taskbar & SoftKeyBar transparency (PPC Only)

#define TSKBM_GETALPHA (WM_USER + 150)

// wParam == 0 (This parameter is not used)

// lParam == 0 (This parameter is not used)

// Return value:The return value is the current alpha value, default is 255 (opaque).

 

// Set the alpha value for taskbar & menubar transparency (PPC Only)

#define TSKBM_SETALPHA (WM_USER + 151)

// wParam == alpha value (0 - 255) 0 == transparent, 255 == opaque

// lParam == 0 (This parameter is not used)

// Return value: The return value is undefined

 

// Set the overlap image for the softkeybar

#define WM_SETSOFTKEYBARBACKGROUND   (WM_USER + 410)

// wParam == alpha value (0 - 255) 0 == transparent, 255 = opaque

// lParam == an image (HBITMAP)

// Return value: The return value is undefined

 

// Set the overlap image for the taskbar (PPC Only)

#define WM_SETTASKBARBACKGROUND      (WM_USER + 411)

// wParam == alpha value (0 - 255) 0 == transparent, 255 = opaque

// lParam == an image (HBITMAP)

// Return value: The return value is undefined

 

// Get the overlap image alpha value for the taskbar (PPC Only)

#define WM_GETTASKBARBACKGROUNDALPHA      (WM_USER + 412)

// Return value: The return value is the overlap image alpha value of the taskbar

 

// Get the overlap image DC for the taskbar (PPC Only)

#define WM_GETTASKBARBACKGROUNDDC      (WM_USER + 413)

// Return value: The return value is the overlap image DC of the taskbar

 

設定標題列和功能表列背景代碼，setVal為透明度

BYTE setVal = 255;

HWND hwndTB = FindWindow(L"HHTaskBar", NULL);

SendMessage(hwndTB, WM_SETTASKBARBACKGROUND, setVal, (LPARAM) m_hTSKImage);

SendMessage（h_Menubar, WM_SETSOFTKEYBARBACKGROUND, setVal, (LPARAM) m_hSOFTKEYImage);
